Mega-Space Current Algebra and Green-Schwarz Geometry in Heterotic String Theory
Machiko Hatsuda, Shin Sasaki, Masaya Yata
We study the Lorentz and gauge connections in heterotic string theories within a framework of manifest T-duality. A central motivation is the Bergshoeff--de Roo (BdR) type parallel…
Gauged Double Field Theory, Current Algebras and Heterotic Sigma Models
Machiko Hatsuda, Haruka Mori, Shin Sasaki +1
We study the generalized metric and the gauge symmetries in the gauged double field theory (DFT) in view of current algebras and sigma models. We show that the $O(D,D+n)…
Five-brane Current Algebras in Type II String Theories
Machiko Hatsuda, Shin Sasaki, Masaya Yata
We study the current algebras of the NS5-branes, the Kaluza-Klein (KK) five-branes and the exotic -branes in type IIA/IIB superstring theories. Their worldvolume theories ar…
Gauge Five-brane Solutions of Co-dimension Two in Heterotic Supergravity
Shin Sasaki, Masaya Yata
We continue to study the BPS gauge five-brane solutions of codimension two in ten-dimensional heterotic supergravity. The geometry including the dilaton and the NS-NS -field are…
Non-geometric Five-branes in Heterotic Supergravity
Shin Sasaki, Masaya Yata
We study T-duality chains of five-branes in heterotic supergravity where the first order -corrections are present. By performing the -corrected T-duality transformations of…
World-volume Effective Action of Exotic Five-brane in M-theory
Tetsuji Kimura, Shin Sasaki, Masaya Yata
We study the world-volume effective action of an exotic five-brane, known as the M-theory 5-brane (M5-brane) in eleven dimensions. The supermultiplet of the world-volum…
